ABSTRACT:
A hearing device has a transfer function adjustable by a set of parameters. The hearing device can have two microphones, a processing unit, and a speaker unit. A direction identification unit is operationally connected to the processing unit. Communication between a user of the hearing device and at least one reference person is ensured for changing positions of the user and/or the reference person. The transfer function is adjusted as a function of at least one current reference person direction by changing the set of parameters. The reference person direction encloses an angle with a reference plane of the user.
